  • Page 2: Amc1204Evm Overview

    The analog input to the AMC1204 is routed from a two-wire screw terminal screw at J4. This screw terminal gives the user access to the inverting and noninverting inputs of the AMC1204. Analog Inputs The analog input to the AMC1204EVM board consists of simple R/C filter circuits. The input circuit for the AMC1204 is shown in Figure...

  • Page 3: Digital Interface

    Digital Interface The AMC1204EVM is designed for use with digital filters such as the AMC1210. The output and power for the AMC1204 are routed to a 9-pin, female D-type connector. Both the analog and digital power for the AMC1204, as well as the modulator data and clock outputs from the device under test, are routed to J2, Figure 2 illustrates.

  • Page 4: Power-Supplies

    This section describes the general operation of the AMC1204EVM. Isolated Power and Analog Inputs: J1 and J4 The isolated power input to the AMC1204EVM printed circuit board (PCB) can be applied directly to J1, pins 1 and 2. Table 2 lists the details of J1.
  • Page 5 Device Operation Once the analog and digital power sources are applied to the AMC1204EVM, the digital outputs become active upon the application of an external modulator clock source. The internal reference of the AMC1204 is used as the conversion reference.
